This is a true story I've been wanting to tell all about for years, we live in a town near york and about 10yrs ago me and the now ex wife were in the middle of our separation all quite amicable we'd just grown apart. anyway as we had a young child we agreed to live in the same house but sleep in seperate bedrooms. Rachael had started to go out in the town on a Saturday night with her friends most of them single as she was as we had split, Rachael was around 40 Brown hair slim with a nice arse 34c tits and huge long erect nipples and a big flirt so she had always had a lot of attention of other men when we used to go out anywhere. I'd previously said to her if she wanted to bring anyone back I wouldn't have a problem with it but she said no as it would be too weird,I still hoped she would as I figured hearing her being fucked by someone else would be a huge turn on, instead she would mostly arrive home around 4ish on her own but obviously well fucked judging by the soaking wet cum stained knickers she left in the wash basket in the bathroom which I just had to wank into as soon as she was asleep. One weekend I was due to go to a surprise 40th in the next town and was going to stay over at my mates house, as Rachael had also arranged to go out our daughter was going to her sisters for the night and to stay over, I'd been drinking since 5 and come home at 11 I was tired and ready for bed and instead of going to my mates house I jumped in a taxi and came home, I arrived home to a dark house went straight up to bed and was nodding off when I heard a taxi stop outside and the sound of rachel giggling I peered out of the window and she was with another man, realising she thought I wasn't coming home I jumped out of bed opened my bedroom door bak to how it was,i straightened the duvet out and hid between the bed and wall. The door shut loudly behind them downstairs it then went quite apart from the frantic kissing I could hear,my cock instantly became rock hard as I knew at last I was going to hear her being fucked, "up stairs" I heard her say to him, "where's dave" he said "away for the night" she replied As she led him upstairs and they turned for her bedroom they stopped on the landing to kiss again I cautiously peered through the gap I'd made between the pillows and headboard, the bloke who was tall towered over her I recognised as my mates brother was kissing her neck and unbuttoning her white blouse as it fell to the floor he put his hand in her bra and freed one of her tits exposing her huge nipple which he started to suck which made her moan loudly. She made him stop and dragged him to her bedroom which incidentally is next door to mine and fell onto the bed, from then on all I could make out was the odd moan or two then I heard shoes and other clothes being flung on the floor,it went quite again then oh yeah she was moaning I love that oh yeah really loudly, he must be have been licking her fanny I figured I daren't touch my aching cock or I would of just cum straight away. After a about ten minutes she was panting and moaning very loudly much louder than she did with me,then more movement it was now his turn to moan the lucky bastard was getting his cock sucked (oh how I miss her blowjobs) yes yes he was saying that's so fucking good,about 5 minutes passed I heard her move as the bed creaked and she was saying I need your cock in me now I need fucking, then he must of entered her as the scream of oh that's so good that's so fucking good was loud enough for the neighbours to hear. I was in heaven hearing her getting fucked senseless by a lad 15 years younger than her was awesome then I heard her say oh yeah I love it this way on then her saying harder harder and the distinct sound of his ball's slapping against her I knew he was fucking her doggy style her favourite, this then gave me an idea my door was open if I crept closer maybe hers would be open enough to see through the crack in the door, I quietly edged to the door and what a sight there he was hands on her hips pounding away while she screamed as she came, I watched in awe as this young lad fucked her senseless. As he then laid on his back and pulled her on top in the lamplight I noticed she had a bald fanny something she would never do for me, she then squat over his very impressive cock much bigger than mine no wonder she was screaming so loud, she slid up and down his cock till she came loudly again, he then flipped her on her back and pounded her for about 5 mins then shot his spunk inside her. As they were panting I quickly went back to my hiding place, 2 minutes later she went to the loo as she came back I saw her bald fanny and them huge long nipples I loved so much which as she disappeared I shot my huge load on the floor. I heard them talking he said he'd wanted to fuck her for ages but he New Martin was fucking her so he didn't try it on with her I Couldn't believe my ears Martin who was he? She said I wish you had your a much better fuck than him, and your cocks much bigger she laughed. How come I'm able to fuck you at home Martin said you had to go to his or up to the pastures in his car. I told you she said Dave's at a party, and I can't believe he told you that. What else has he told you? He laughed and said, only that you love cock and give great head.... I heard her laugh and give him slap. I was gobsmacked. There is a part two if you want to read ot
